The present invention relates to a window sash and has for its principalobject to pro vicle a structure formed of all metal parts sons to befire proof, strong, and durable,

"Figure 3" is a fragmentary rear elevation rigid, thoroughly efficientand a reliable in use, relatively inexpensive to manufacture, easy toassemble, and otherwise well adapted to the purpose ''for which it isdesigned. "With the above andnumerous other objects' in view as willappear asthe description proceeds, the invention residesincertainnovel'features of'construction, and in the combination andarrangement of parts as well'be hereinafter more fully described andclaimed; In the drawings i I v 7 Figure 1 is a fragmentaryfrontielevation of the sash embodyingthefeatures of my invention,

Referring to the-drawingin detail it will be seen 'thzitthe' lettersl'Aqdenote generally the'top, bottom; and side rails of thesash, whilethe letter B denOtesthe cross joint between the side rails forconnecting the panesof glass The rails are disposed to form arectangular sash and are of the 'same construction as far. as. theessence of the ,invention is concerned varying only as to directed tothe bottom rail shown in Figure 7 their 'lengthQ-and it is thought thata detail description one. of the, rails will suflice for all. I

Referring. therefore. to one of the rails in -detail it will be seenthat itis formed from a single .strip rof sheet metal material whichis'bent along certain parallelspaced longitudinal. dimensions, In thisdetail description of asingle rail particular attention is I2. ,Theouter plate 5 of thisrail merges at its inner edge into the inner plate6 whichmerges into a portion overlying the plate 6 a verticallongitudinal section tor-a distance as, is indicated at-7fand merginginto a portion8: which overlies theportion 7 in spaced parallelismthereto, the 'porj of the plate 5 is curved downwardly as at12-and1merges into a portion 13 disposed at an obtuse angle respect tothe outer surface of the outer plate 5. Thispor-tion ion.

This outer plate merges into a portion 16 disposedobtuselytoth e inner surface of the outer plate 15 which merges-into anoverlapping portion 17 This'portion 17 merges into an overlapping spacedparallel portion .l8 fo'rming with the portion 17 a pocket for receivingthe tongue, terminals 11'. The rails Aare held together by means ofcorner pieces 19.-one'ot which isshown in detail in Figure 7 and theposition therelongitudinal dimensions 20 and 21 to form an'intermediatebody portion22. having at one edge an obtuse "exte'nsion23 and atsitfs'other edge an acute extension 24- Theobv .tuse extension, 23 is adaptedtobe rece1ved in the, pocket formed by overlying portions 7 and 8,while' the acute'extens'ion 24-fis adaptedito engage tliepane C. Puttyor like packing material is adapted to .beplaced beof is indicated indotted lines in Figure,.3.- The letters 1) denote pointer strips whichare vformed of sheet metal bentalong-the tween the portions 10 and 17and the'adjacentportion of the paneG'as is indicated in Figure 2. a Itis to be'not-ed thatt'here is a slight difference between the side andtop rails and the bottom rails which maybe ascertained by referringparticularly to Figure 2 wherein'it will be seen that the portions '13and 14bit the bottom rail are dis whereas in the top rail and in theside. rails these portions 13 and 14; are disposed at right angles tothe plate 5 andrin parallelism with. plate 15.

.105 posed obtusely to'the plates 5 and15 and The joint cross'pieceB'includes generally three members shown respectively in'TFigures 4,15and 6. The member shown in Figure 4: is in the inside member, and 1sformed "from a single sheet of metal bent along parallellongitudinaldimensions 26 and 27 to provide an intermedlate plateportion 28 merging at its edges into obtuse extensions 7 '29 each ofwhich is bent inwardly over upon itself as at 30, The member shown inFigure is bent along spaced parallel longitudinal dimensions 31 to forma center strip plate 32 vvhich merges into obtuse extenv sions 33 whichare bentover upon themselves to form u shapedextensions 34 that providepockets. The member shown in Figure 6 is bent along spaced parallellongi tudinal dimensions 35 to provide a center strip 36,which merges atits edges into acutely disposed extensions 87 adapted to be received inpockets 34 as is clearly shown in Figure 2. Themembers shown in Figures5 and 6 form'the outside portion of the joint piece, while the membershown in Figure 4 forms the inside piece thereof. Screws 38 q pierceopenings 39 in the'plate portion 28 and pierce'the strip "plate 36.Packing such as puttyor the like may be interposed betweenthe twopanes'which are held in place I claim as new and by these joint membersas clearly shown in Figure 2. i i v g i j All parts of this window sashare formed fromlsheet metal bent in the manner described. The sash thusformed is fire proof,

strong, durable, and rigid, and will therefore prove thoroughlyefficient and reliable in use. It is thought that the constructio'n,utility, and advantages of the all metal .sash willnow be clearlyunderstood without amore detail description thereof. It is to I beunderstood, of course, that the joints of the various rails and crossjoint pieces may be soldered together in the well known mannerivThe'present embodiment of the invention has beendisclosed in detailmerely by wayof example since in actual practice it at-- "tains thefeatures of advantage enumerated 'a's desirablein the statement of theinven-' -tion, and the above description.

parent that the changes in the details of construction, and in thecombination and arrangement of parts may be resorted to with outdeparting from the spirit or scope of the invention as hereinafterclaimed or sacri- :ficing any of its advantages.

"Having thus described my invention, what desire to secure by LettersPatent is 1. A window sash'of the class described l includingaplura-lity of rails, each rail being formed'from a single sheet ofmetal bent alongp'arallel spaced longitudinal dimen "sions to, formahollow construction having an outer plate merging at'its inner edgeinto a right angularly extending inside plate.

which merges into an overlapping portion It is apthat is bent over uponitself and merges nto an. inner plate disposed in parallelism with the.outer plate and at right angles to the inside plate,-said inner platemerging into an inwardly directed right angular extension merging intoan outwardly disposed acutely extending tongue, the outer edge of theouter plate merging into an overlapping extension which in turn mergesinto an outside plate extending perpendicularly to the outer plate andmerging into an obtuse extension overlapping itself and having a spacedoverlapping portion for forming'a pocket to receive the tongue I 2. Awindow sash of the class described including a plurality of rails, eachrail being formed from a single sheet of-metal bent along parallelspaced longitudinal dimensions to form a hollow construction having anouter plate merging at its inner edge into a right'angularlyextendinginside plate which merges into an overlapping portion that isbent over upon itselfand merges into an inner plate disposed inparallelism with the outer plate and at rightpangles'to the insideplate, said inner plate merging into an inwardly directed right angular"extension merging into an outwardly disposed acutely extending tongue,theouter. edge'of the outer plate merging into an overlappingextensionwhich in turn merges into an outside plate extending perpendicularly tothe outer plate and merging into an obtuse extension overlapping itselfand having a" spaced over- .plate having obtuse extensions merging intoinwardly disposed U-shaped portions to form pockets, the other outsidemember being formed from asingle sheet of metal bent to provide a centerplate and edge acute extensions receivable in the pockets, said innermember being formed from a single sheet of metal bent to provide acenter plate having obtuse extensionsbent inwardly over upon themselves.r
